The @CodSpeed agent is getting pretty good doing perfomance work. Here x2-3 on @biomejs formatter.

Proud to announce that @CodSpeed has joined the Rust Foundation as a Silver member!
Weβre all-in on making Rust (and everything around it) fast and staying that way. Supporting the Project that makes that possible felt like the obvious next step.

Significant `jiter` release, in particular this includes SIMD support for x86, which should give up to 7x performance improvement for parsing long strings.
There are also significant improvements for tape reuse, arm64 string SIMD, float parsing and more.
jiter is the most used 3rd party JSON library in Python as a dependency of @pydantic validation.
it's also used in Pydantic Monty, and in Pydantic Logfire via datafusion-functions-json.
Short story: apply strict constraints, provide clear benchmarks for the thing you want to improve, use @codspeed, let fable and astra do their thing.

Let's welcome @codspeed and @Cloudflare new Gold and Silver sponsors of the project! π

π₯ @codspeed: the performance platform that catches regressions before they hit production, autonomously suggesting and validating optimizations across CPU modeling, profiling, heap analysis, and more. Free for open source.
Thank you for supporting #rustconf at the Gold Level, CodSpeed! codspeed.io

tfw you spend a few hours optimizing and you finally see the @codspeed GH action report

Your benchmark moved. You didn't touch the code.
A compiler bump, a new system lib, a different CPU flag. Any of it shifts the numbers.
CodSpeed now diffs the environment between two runs, so you know when it's the toolchain that changed and not your code.

.@codspeed uses Claude Managed Agents + @blaxelAI sandboxes to build an AI agent that:
-> ingests customer code
-> benchmarks it
-> iterates on changes
-> finds performance improvements
xitter.cf/ClaudeDevs/status/2065β¦
Claude Managed Agents can operate in a sandbox you control, on your own infrastructure or with any provider you choose.
Today we added new guides for @blaxelAI, @e2b, @googlecloud, @namespacelabs, and @superserve_ai, so you can choose the best fit for your use case.

"I use it every day and honestly can't live without it. Saves me tons of time."
@hardfist_1, lead of @rspack_dev at ByteDance, on the CodSpeed Wizard.
So proud and excited to build the performance agent for the fastest projects on the planet!

"If you're gonna ship slop, at least make it fast."
Our top sticker at PyCon and there's a reason: code has never been cheaper, reviewers are under pressure and regressions are piling up.
Stop thinking about performance, we'll make your thing faster.

Claude Code can now improve performance and fix regressions.
The CodSpeed plugin just landed on the official marketplace.
Try it out: /ππππππ πππππππ ππππππππ@ππππππ-πππππππ-ππππππππ

i pair it with spec driven dev, coderabbit reviews on PR, and a lot of unittests, snapshots tests and codspeed tests and yes it's quite good. I was hesitant but running on it everywhere now

/goal for finding silly one-line optimizations that speed up your parser by 20-30%
CodSpeed retweeted
Things get wild when @hardfist_1 uses Codex.
He just made SWC parser 20% faster and minifier 10% faster π€―

Had a great time on the @pybites Podcast with @bbelderbos talking about what pushed me to build @codspeed. From building an ODM for MongoDB to obsessing over software performance.
We cover the genesis of CodSpeed, Python perf, and why catching regressions early changes everything.
